MACHINE FOR MAKING BINDING-STRIPS.

SPECIFICATION forming part of Letters Patent N 0. 499,551, dated June 13, 1893.

Application filed September 1, 1892. Serial No. 444,787. (No model.)

To all whom it may concern:

Be it known that I, AUGUSTUS R. KELLER, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented an Improved Machine for Making Binding- Strips, of which the following is a specificanon.

The object of my invention is to provide an improvement in a machine for manufacturing flexible guards or strips for book binding, such for instance as employed in the manufacture of flat opening blank books, albums, 850., and this object I attain in the manner fully set forth hereinafter.

In the accompanying drawings:Figure 1, is a longitudinal section on the line 1-2, Fig. 2, of a machine to which my improvement is applied. Fig. 2, is an end elevation of the same. Fig. 3, is a view of the'feed roll. Fig. 4, is a perspective View of a detail of the loose disk of the feed-roll. Fig. 5, is an enlarged perspective view of part of aguide employed with the machine.

In the manufacture of certain forms of fiat opening blank books, albums, &c., the leaves are connected to the back by flexible guards or binding strips, usually composed of a series of strips of spaced card board covered on either side by a strip of muslin or linen, the spaces between the sections of card board acting as hinges so that the back whenopen will lay with the leaves flattened out.

The object of my invention is to manufacture thesestrips in large quantities and in a much more economical manner than they can at the present time be made.

Referring to the drawings, A A representrespectively rolls containing strips of fabric, such as linen or muslin, the strips being led over a series of guide rolls a a or a a, a and over rollers B or B, portions of which dip into the paste in paste boxes 0 or O, the strips being guided from the rollers B B between pressing rollers D D and E E which may or may not be of elastic material so long as they impart sufficient pressure to cause the strips :1: w to adhere in the spaces between the interposed strips y. The rollers D and E are preferably mounted in bearings cl which are adjustable from and toward the rolls D, E by means of set screws e e. The rolls A A are provided with friction bands G G having adjusting screws g and the fabric is drawn from said rolls over the paste rollers and through the pressing rollers D D and E E and finally wound up on a receiving roller H mounted in suitable bearings on the opposite end of the machine and rotated in the direction of the arrow by any suitable mechanism.

I represents a roll or shaft mounted in suitable bearings 2' on the frame of the machine, and situated midway between the rolls A A. Mounted loosely on this roll I are a large number of disks as shown for example at 70', Fig. 4 preferably made of thin sheet metal all of the same thickness, although if desired the disks may vary in thickness and may be removable from the end of the roll during the adjustmentof the parts, as will be presently described. These disks serve to space the rows or strips of card board y which are held between the two strips a: a: of fabric.

In the manufacture of the guards it is desirable to employ strips y of varying width, and where necessary to vary to a greater or less extent the space between such strips and to that end I first place one or more of the disks is against the adjustable collar Z on the shaft or roll I and then place around this shaft or roll a roll of card board r of the required width. I then place next to this roll of card board one, two, three, or more of the disks 7.; until the total thickness of the disks so adjusted is equal to the desired width of space between the first and second strips of card board. A second roll of card board is then placed on the roll I, and then another series of the metallic disks,the number of which in each set will depend upon the width of space desired between the strips, the operations being repeated until the entire width of the roll has'been filled when the collars Z are clamped and held in position upon the shaft, as shown in Fig. 2, and alternate strips may be wound in difierent directions so as to provide the necessary friction to keep the strips taut. If desired, however, the disks I may be made of difierent thicknesses and a disk of the proper thickness may be placed between the successive rows of cardboard, this, of course, necessitating that the disks shall be slipped on the end of the shaft one afterthe other, while in the construction first described, the whole series of thin metallic strips may rest loosely on the shaft and any desired number be selected. The strips thus separated are fed between the paste covered strips ac and fed between the rollers D D, E E and the compound strip finally wound upon the roll H. From thence it may be taken and cut into strips of suitable size as required.

It is advisable in most cases to use in advance of the presserrolls D D a guide J for the strips y, this guide being preferably composed of upper and lower perforated bars 121. and pins 11. passed through corresponding perforations of said bars, these pins being properly spaced laterally to accord with the varying widths of the strips y, as shown.

In practice it may be desirable in some cases to employ grooved rollers to press the fabric strips and the card board together, the projecting portions of the rollers corresponding to the spaces between the strips so that the two fabric strips will be pressed together at such points and the grooved rollers may, if desired, be made in a manner similar to the rollers for the card board strips or the rollers may be made of elastic material which will press upon the fabric strips with sufficient force not only to unitethe strips to the card board, but to each other.

Although I prefer in all cases to use the arrangement of guide rolls, paste boxes and pressure rolls as shown and described, it will be evident that the main features of my invention would be embodied in a machine in i or in which on the other hand two sets of rolls were used, one set acting only on the filling strips and one of the strips of fabric, the other strip being directed for instance as shown by dotted lines on Fig. 1.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. A strip feeding roll for machines for making binding strips, comprising a roll or shaft, as 1, adapted to support the series of rolls of filling strips, and independent separating disks mounted loosely on the roll or shaft and unconfined longitudinally whereby they are adapted to space the successive rolls of filling strips and are separated solely by said strips, substantially as specified.

2. A strip feeding roll for machines for making binding strips comprising a roll or shaft, as I, adapted to support a series of rolls of filling strips, and spacing disks adapted to be placed between such rolls, each of such spacing disks being formed of a number of separate and independently movable sections, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

AUGUSTUS R. KELLER.
